| 摘 要： | 冻结轨道是一种稳定的轨道,地球、火星、月球的卫星因引力场的南北不对称,都存在冻结轨道.由于主星体引力场的不同,它们卫星的冻结轨道也有不同的特性.地球卫星的冻结执道的偏心率非常小,对卫星遥感非常有利,国内外已有相当多的近地遥感卫星采用这种轨道.月球卫星的冻结轨道偏心率随轨道倾角的不同有很大的变化,对月球卫星冻结轨道的研究...

| Abstract: | Because of their north-south asymmetry gravity field,there are frozen orbits for satellites of Mars as well as those of Earth and Moon.The frozen orbit is stable and very useful for quite a few space missions.The eccentricity of the Earth frozen orbit is very small and very good for near-earth remote sensing satellites.For lunar frozen orbits,the eccentricity widely vary according to orbit inclination,and a detailed analysis is important for mission design.The Mars is another very important goal of explorat... |
